Hornady 30 Cal 220gr InterLock RN (Bulk / OEM)

Hornady 30 Cal 220gr InterLock RN

The Hornady 30 Cal 220gr InterLock^® RN (Round Nose) is a classic heavy-for-caliber bullet designed for deep penetration, reliable expansion, and optimal performance in medium to large game applications. Its traditional round nose profile makes it particularly effective in slower velocity cartridges such as the .30-40 Krag, .30-06 Springfield, or .308 Winchester when deep penetration on heavy-bodied animals is a priority. Built with Hornady’s trusted InterLock^® technology, this bullet retains mass and delivers consistent terminal performance across a wide velocity range.

Designed with an exposed lead tip, this bullet expands reliably upon impact, while the heavy 220-grain weight ensures momentum is carried deep into vital organs and through thick muscle or bone. The secant ogive profile, though subtle in the RN design, still contributes to stable flight characteristics and improved accuracy for shorter to mid-range shooting.

At the heart of the bullet is Hornady’s InterLock^® ring, a raised internal ridge that mechanically locks the lead core and copper jacket together. This design prevents separation during expansion and maintains the structural integrity of the projectile as it transfers energy into the target. Internal grooves further assist in controlling expansion while allowing the bullet to open consistently under a wide range of impact velocities.

The jacket is tapered and precisely formed to support expansion without over-fragmentation. Hornady applies a cannelure before final forming to help with consistent crimping, which enhances performance in cartridges subject to heavy recoil or loaded in tubular magazines. The Hornady 30 Cal 220gr InterLock RN is also available in bulk bullets packaging, making it a practical and cost-effective option for hunters who handload in quantity.

INNER GROOVES

Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.

TAPERED JACKET

Jacket thickness is precisely controlled for expansion at all velocities.

ONE-PIECE CORE

Does not separate like two-piece divided cores. The InterLock^® retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills.

CANNELURE

Provides accurate and consistent crimping and works with the InterLock^® ring to ensure the core and jacket remain locked during expansion.

INTERLOCK^® RING

The raised InterLock^® ring is embedded in the bullet’s core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy.
